Digital Refrigeration Gauge (Dual Gauge Type)
Model: FDPG-2-S1

Introduction
FDPG-2-S1 dual digital refrigeration gauge can simultaneously display pressure and temperature on LCD screen. It also applicable to measure vacuum pressure. FDPG-2-S1 is suitable in pressure and temperature measurement for non-corrosive refrigeration, liquid and alcohols. It has been widely applied in vacuum refrigeration system assembly and maintenance operation.

Features
■ Dual digital refrigeration gauge with four 1/4”SAE and one 3/8”SAE connections to separately display pressure and temperature from different refrigerant source
■ Maximum measurable pressure 725psi
■ The hook design ensures easy-storage and prevents gauge from external impact.
■ 9 types of applicable refrigerants
■ 4-digit LCD screen with backlight, high refresh rate
■ Auto switch unit to inHg once vacuum pressure is detected
